BAG-LOC K.

SPECIFICATION forming part of Letters Patent No. 693,251,6.ated February 1 1, 1902.

Application filed November 9, 1901. y Serial No. 81,712. (No model.)

To @ZZ whom it may concern,.-

Beit known that L WILLIAM A. FINN, a citizen of the United States, and a resident of Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Locks for Mail-Bags and other Purposes, of which the following is a specification.

The object of this invention is to provide a cheap, simple, efficient, and easily-operated fastener for mail-bags or like articles; and it comprises a lock so arranged in connection with the flap that no strap is required in closing and locking the bag; but it is so arranged that the lock itself has a finger which passes through the slot or opening in the flap andis then turned around in such a position that it locks and holds the flap, all of which will now be set forth in detail.

In the drawings, Figure 1 is a perspective view of the upper end of a mail-bag, showing the locking-fingers in position; Fig. 2, a vertical cross-section of a bag with the lockingfinger turned down andshowing the relative position of the slot in the flap;Y Fig. 3, a sectional view of the lock attached to the body of the mail-bag with the nger locked in one position, and Fig. 4 a sectional view of the lock with the key applied to unlock same.

In constructing my invention I prefer to have the mail-bag 5 provided with a flap 6, which has a series of vertically-disposed slots 7 near its lowery end, these slots being so located that the fingers S of the lock will readily pass through when the fingers are turned up to a vertical position, as shown in Figs. 3 and 4.

The lock itself is attached tothe front body 9 of the mail-bag. It comprisesabase-plate 10 of suitable size, to which is attached or cast therewith the tubular shell 11, which is of suflicient lengh to providev for the thickness of both flap 6 and Jbody 9 of the bag. This shell has oppositely-disposed notches or detents 12. yWithin this shell is fitted a cylinder 13, having at its rea-r end a disk head 14, and its forward end projects beyond the end of the shell 11 and passes through and is rigidly attached to the finger 8 by being riveted thereto, as at 15, or otherwise. This cylinder is so placed within the shell 11 that it will readily turn. A longitudinal slot 16 is formed on one side of the cylinder 13, within which is hinged a bell-crank lever,`one end of the bell-crank lever having a point or nib 17, which is designed to enter the notches 12 in the shell, and opposite thereto iis a point or nib 18, which enters the notch 19 of the key 20. y The other limb of the bell-crank lever has a nib, which is designed to engage with the end of the key, and behind this limb is a spiralspring 20, designedto normally throw outthe other limb of the lever and keep the nib 17in engagement with the notch in the shell. The key 20 is so designed that Whenit is`placed`in the slotted aperture of the lock the endthereof will press against one limb of the bell-crank lever, thus disengaging the otherlimb of the lever and permitting the cylinder to turn, and when the cylinder is thus rotated one-half of a revolution the nib 17 on the bell-crank lever will engage the other notch in the shell.

Any form or characterof lock and key suitable for the purpose may be employed, and I merely sh'owa typical form herein to illustrate the manner of applying and operating the same.

What I claim as new isl. A fastener for mail-bags comprising a tubular shell attached to the body of a mailbag, having therein a rotatable cylinder provided with a projecting finger on its outer end, Aand locking mechanism Within said cylinder, in combination witha flap on said locking-cylinder, said slot being so located as to receive the linger therein only when the' cylinder is unlocked, as set forth.

2. A lock for mail-bags or similar articles, comprising a tubular shell open'at both ends integral with a base-plate, having interiorly oppositely disposed detents, in combination withau interior rotatable cylinder provided at its forward projecting end with a finger, a bell-crank lever within said cylinder hinged within a recess, one limb of said lever having a. nib to engage with the detente of the Signed at New York, in the County of New outer shell and a. nib to enter the notch of a York and State of New York, this 4th day of key on its other side, and the other end of October, A. D. 1901.

said lever having a nib to engage with the WILLIAM A. FINN. key, and :L spring to normally keep the bell- XVitnesses:

crank lever in engagement with the detenL-s J. S. ZERBE,

in the outer shell,l as seb forth. i R. THOMPSON.
